▸Output

- Message: The virtual environment was not created successfully because ensurepip is not available.
  - On Debian/Ubuntu: install python3-venv package.
  - Command to fix (example): apt install python3.10-venv (may require sudo); after installing, recreate the virtual environment.

- Failing command/step:
  - Dockerfile step [6/6] RUN python3 -m venv .venv   && . .venv/bin/activate   && pip install --upgrade pip setuptools wheel maturin   && maturin develop -m py-polars/runtime/polars-runtime-32/Cargo.toml
  - Failing command path: /workspace/.venv/bin/python3

- Missing packages or files:
  - python3.10-venv (recommended)
  - python3-venv (also relevant)

- Version/environment details:
  - Base image uses Ubuntu (jammy) and attempts to install Python 3.10 components.
  - Error explicitly points to missing python3.10-venv as the fix, not a code mismatch.
  - Cause: ensurepip unavailable because venv creation failed due to missing venv package.

- Recommended fix:
  - Add installation of the Python venv package in the image before creating the virtual environment, e.g.:
    - apt-get update && apt-get install -y python3.10-venv
    - (or) apt-get install -y python3-venv
  - Then re-run the build.

- Runtime note:
  - If you expect imports without activating the venv, consider installing into system Python or exposing the venv’s bin/python via PATH or activating it in CMD.

Concerns: Final runtime image only installs ca-certificates and copies the Python virtual environment. The polars Python extension likely requires runtime system libraries (e.g., libssl, zlib) to be present in the final image. Without these, importing polars may fail due to missing shared libraries., Potentially very long build time in the builder stage due to building Rust/Python extensions; consider caching layers or a multi-stage cache strategy., The maturin build target path (-m py-polars/runtime/polars-runtime-32/Cargo.toml) assumes a specific repository layout; ensure this path exists in the monorepo and is consistent across branches.

Concerns: Final runtime stage installs only ca-certificates; Polars Python bindings may depend on additional shared libraries (e.g., libzstd, liblz4, libssl, etc.) at runtime. If these are not present in the final image, loading the Python extension could fail., COPY . . in the builder stage copies the entire repo. Ensure a proper .dockerignore to avoid bloating the build context and accidentally including sensitive or large files. Also verify that the path py-polars/runtime/polars-runtime-32/Cargo.toml exists in the repo to avoid build failures.

▸Build error

Summary (under 1500 chars):

- Exact error message and exit code
  - The virtual environment was not created successfully because ensurepip is not available.  On Debian/Ubuntu systems, you need to install the python3-venv package using the following command.
  - 
    apt install python3.10-venv
  - You may need to use sudo with that command.  After installing the python3-venv package, recreate your virtual environment.
  - Failing command: /opt/venv/bin/python3
  - 
    ERROR: process "/bin/sh -c python3 -m venv /opt/venv" did not complete successfully: exit code: 1

- The failing command/step
  - [builder 4/8] RUN python3 -m venv /opt/venv

- Missing packages or files mentioned
  - The error implies ensurepip is unavailable because the venv tooling is not installed. Install python3-venv (specifically python3.10-venv for this image) to enable ensurepip and allow python3 -m venv to succeed.

- Version mismatch info
  - The build uses Ubuntu jammy with Python 3.10.x (e.g., python3, python3.10, python3.10-minimal, etc.). The log’s guidance references python3.10-venv, indicating a version-specific venv package is needed. No explicit Python version mismatch is shown beyond the need for the appropriate python3.10-venv package.

Concerns: The build target is a 32-bit Polars runtime (polars-runtime-32) but the final image uses a 64-bit Python interpreter and libraries. Without enabling 32-bit multiarch support or building a 64-bit variant, the produced extension is unlikely to load correctly in the final image (ELF class mismatch or missing i386 libraries). This risks runtime failure when importing polars.

  - Message: Couldn't find a virtualenv or conda environment; need one to use this command
  - How to satisfy: set VIRTUAL_ENV (activate virtualenv), or set CONDA_PREFIX (conda activate), or have a virtualenv named .venv in the current directory or any parent
  - Alternative: run maturin build and pip install <path/to/wheel> instead
- Missing/affected packages/files: no Python virtual environment found; no VIRTUAL_ENV set; no .venv in current or parent folders
- Version information:
  - Rust toolchain: Rust 1.94.0 (stable-x86_64-unknown-linux-gnu)
  - maturin: 1.12.6 (via pip)
  - Python: Python 3.10; virtualenv expected at /opt/venv (created earlier in Dockerfile)
  - Note: maturin requires an active/recognized virtualenv in the current context
- Context:
  - A venv was created at /opt/venv earlier; maturin develop could not locate an active virtualenv in the workspace
- Quick fix suggestions:
  - Create/activate a virtualenv named .venv in the current or a parent directory, or export/activate an existing one (set VIRTUAL_ENV)
  - Alternatively, run maturin build and install the resulting wheel instead of maturin develop

Summary (under 1500 chars):

- Failing step: [builder 8/8] RUN maturin develop -m py-polars/runtime/polars-runtime-64/Cargo.toml

- Exit code: 1

- Exact error message and exit code:
  💥 maturin failed
  Caused by: Couldn't find a virtualenv or conda environment, but you need one to use this command. For maturin to find your virtualenv you need to either set VIRTUAL_ENV (through activate), set CONDA_PREFIX (through conda activate) or have a virtualenv called .venv in the current or any parent folder. See https://virtualenv.pypa.io/en/latest/index.html on how to use virtualenv or use `maturin build` and `pip install <path/to/wheel>` instead.

- Failing command/step details:
  RUN maturin develop -m py-polars/runtime/polars-runtime-64/Cargo.toml

- Missing packages or files mentioned:
  No virtualenv or conda environment found. Required to set VIRTUAL_ENV (through activate) or CONDA_PREFIX (through conda activate), or ensure a virtualenv named .venv exists in the current or a parent directory.

- Version mismatch info:
  None reported. The build uses ubuntu:jammy-20260217 as the base image, but there is no version mismatch error indicated in the log.

Concerns: Building a 32-bit Polars runtime (py-polars/runtime/polars-runtime-32) on a 64-bit base may require 32-bit toolchains/multilib which are not installed by default. Build could fail on architectures without multilib support., FROM image tag (ubuntu:jammy-20260217) is a dated tag. Ensure this tag exists in the build environment or pin to a stable digest to avoid build failures., No explicit version pinning for maturin or Rust/Cargo; updates could change build behavior. Consider locking toolchain versions to ensure reproducible builds.

Concerns: COPY --from=builder /workspace/target/wheels/*.whl /wheels/ likely uses a glob pattern that Docker's COPY may not expand. This can cause build failures. Consider copying the entire directory (e.g., /workspace/target/wheels/) to /wheels/ and then install with /wheels/*.whl.

Concerns: The wheel output path from maturin is likely under the crate directory (e.g., /workspace/py-polars/runtime/polars-runtime-64/target/wheels). The Dockerfile copies from /workspace/target/wheels, which probably does not exist, causing a COPY to fail., The chown -R appuser /usr/local/lib/python3*/site-packages runs before wheel installation, which may not exist yet and could fail; consider moving this after pip install or using a safer path.

▸Build error

Summary:
- Exact error message and exit code
  The virtual environment was not created successfully because ensurepip is not available. On Debian/Ubuntu systems, you need to install the python3-venv package using the following command.

      apt install python3.10-venv

  You may need to use sudo with that command.  After installing the python3-venv package, recreate your virtual environment.

  Failing command: /workspace/.venv/bin/python3

  Exit code: 1

- Failing command/step
  RUN /bin/bash -lc 'set -e;     python3 -m venv .venv;     source .venv/bin/activate;     python -m pip install --upgrade pip setuptools wheel maturin==1.4.0;     maturin develop -m py-polars/runtime/polars-runtime-32/Cargo.toml'

- Missing packages or files mentioned
  - python3.10-venv is needed (as suggested by the error). The installer prints: apt install python3.10-venv

- Version mismatch info
  - maturin pinned to 1.4.0 in the failing command
  - Python environment shown includes Python 3.10.x (e.g., python3.10, python3.10-minimal, etc.), indicating the missing venv component prevents using ensurepip for venv creation. No explicit mismatch but a missing python3.10-venv package is the blocker.
